摘要 :
Techniques and mechanisms for configuring services which variously facilitate data protection. In an embodiment, circuitry coupled to a memory comprises both a first circuit which calculates integrity information based on data, and a second circuit which evaluates data validity based on such integrity information. A configuration of the circuitry provides a combination of one or more services which is specific to a corresponding domain of the memory. With respect to accesses to the corresponding domain, the configuration prevents an access to the first circuit while an access to the second circuit is permitted. In another embodiment, a processor signals the circuitry to transition to another configuration which, with respect to accesses to the corresponding domain, permits access to both the first circuit and the second circuit.
